Other objects and advantages of this invention will be apparent during the Course of the following description.

ln the accompanying drawings forminga part of this specification and in which like numerals are employedV todesignate like parts throughout the same, Figure 1 is a side vlew of the complete table, Fig. 2 is a transverse sectional/view taken on line 2-2 of Fig. 1 and looking in the direction of the arrow, Fig...3is a similar View taken on line 38 of Fig. 1" and lo-oking in the direction of the arrow, Fig. 4t is a central vertical longitudinal 'sectional view through the complete table', Fig. 5 is a horizontal sectional view taken on line 5-5 of Fig. 4, Fig. 6 is an end view of the front table top, Fig. 7 is a plan view of the complete table, Fig. 8

is an end view of a forward spring, parts being broken away, for the sake of illustration, Fig. 9 is a side View of the same, Fig. 10 is an end vie'w of a 'rear spring, Fig. 11 is a side view of the same. Fig. 12 is a perspective view of the sternum support and zontal portion 15 and a rear slightly inclined portion 16, as clearly shown in Figs. 1 and 4. Connected with the forward end of the longitudinally extending tubular rods 13 are depending feet 17, the upper ends of which are connected by a transverse rod or bar 18. These feet 17 are preferably provided at their lower ends with caps 19, which may be formed of rubber or other similar material. Longitudinally movably mounted upon the rear ends of the longitudinally extending tubular rods 13 is a foot rest o-r support 20, which is preferably formed of iron or some other heavy material to counterbalance the vertically swinging supporting structure 12, as will be hereinafter apparent. Connected with the outer surface of the foot rest or support 20 are ipeaave legs 21, carrying caps 22 which are formed of rubber or other similar material. Connected with the inner surface of the laterally extending foot rest 20 are'longitudinally extending rack-bars 20a, provided at their free end portions with teeth 20", which are engaged by pinions 20C, which are in turn rigidly mounted upon a transverse shaft 20d. This transverse shaft 20d is provided at both ends with'. handles or wheels 20er, by means of which the same may be turned. lt is thus seen` that by rotating the shaft 2Od in the desired direction, the laterally extending foot rest 20 may be made to travel longitudinally of the tubular rods 13. Any suitable means may be employed to prevent theimproper or accidental rotation of the shaft d. The shaft 20d is mounted through bearings 20f, disposed be- 20 tween transverse bars 77 and 7 7 vand rigidly attached thereto, said transverse bars being provided with apertures for receiving the portions 16 of the longitudinally extending rods 13. Connected with lthe rear end of the stationary supporting frame 11 is a transverse shaft 23, upon which are pivotally mounted brackets 24, the same being provided with openings for receiving the portions 16 of the longitudinally extending tubular rods 13, such portions 16 being rigidly held therein by means of clamping bolts 25 or the like. It is thus seen that the ,supporting structure l2 will swing or turn in a vertical plane upon the shaft 23 as a pivot, the foot rest or support 20 passing downwardly between the sides of the stationary supporting frame l1, sothat the supporting structure 12 may assume a substantially vertical position, with the feet 21 in engagement with the floor. y The numeral 26 designates a rear auxiliary frame, which is longitudinally movably mounted upon the portions 16 of the longitudinally extending tubular rods 13. This rear auxiliary frame com rises brackets 27 and28. The brackets 2 and 28 are connected by longitudinally extending rods 31, as shown. Any one of the brackets 27 and 28 may beprovided with a clamping bolt 32, to lock the rear auxiliary frame 26 A ,to the portions 16 in adjustment at desired longitudinal positions with relationrthereto.' Disposed above and supported by vthe brackets 27 and 28 isa rear tabletop 33,

which is preferably padded or upholstered in any desired preferred manner. The for- 'ward brackets 28 have no connection with the forward end ofthev rear table top 33,

, while'the rear brackets 27 are hinged to the table top 33, as shown at34. It is thus seen .that the rear table top 33 is capable of being angularly adjusted or swung in a vertical plane, uponthe hinge 34 as a pivot, with relation to the rear auxiliary frame 26.

Disposed adjacent the forward brackets 28 The side pieces 44 comprise upwardly exis a vertical adjusting element 35,. disposed below the forward end of the rear table top 33 and extending transversely thereof in engagement therewith, This vertically swinging adjusting element 35 is provided with .,O apertured ears 36, through which extend a transverse rod 37, the same also passing through openings formed in the brackets 28. This transverse rod 37 is provided with v right and left screw-threads, carrying nuts 38 and 39 which are adapted to clamp the apertured ears 36 against thebrackets 28,

to lock the element 35 in a justment at desired angular positions. The nuts 38 and 39 are provided with apertured extensions, mi receiving a rod 41, attached to the brackets 28, for preventing the rotation of said nuts. The rod 37 is provided at both ends with operating handles or wheels 42, as shown.

It is thus seen that by unscrewing the transg5 verse rod 37, the rear table top 33 having its forward end elevated to the desired position, the adjusting element 35 may be swung upwardly in engagement therewith, subsequently to which the transverse shaft '9g' 37 may be turned to lock the element 35 against downward movement.

The numeral 43 designates a forward auxiliary supporting frame as a whole, which is longitudinally adjustable upon the forward portions 15 of the tubular rods 13. This forward vauxiliary supporting frame comprises spaced side pieces 44, carrying depending sleeves 45, which receive the portions 15 of the tubular rods 13 therethrough. Clamping bolt orbolts 46 may be employed to lock the' auxiliary supporting frame/43 in adjustment at desired positions with relation to the longitudinal tubular rods 13.

tending inverted V-shaped supports47, disposed outwardly of ears 48, formed upon a transverse strip 49, these parts being pivotally connected by bolts 50 or the like. The transverse strip 49 is rigidly connected with the lower surface of av forward table top 51, by means of screws or bolts 52 or the like. This forward table top is preferably suitably padded or upholstered. Rigidly connected with the lower surface of the forwardtable top 51 forwardly of and spaced from the trhnsverse strip 48, is a transverse strip 53,l carrying depending apertured ears 54, which are pivotally connected with de- Y pending links 55, by means of transverse 120 bolts 56, as shown. The links 55 are provided with longitudinally extending slots 57, for receiving therethrough a transverse rod 58. This transverse rod 58 is rotatably mounted throughthe upper portion of the forward sleeves 45. The rod 58 is provided at both ends with handles or wheels 59. The rod 58 is provided adjacent and in-d wardly of the links 55 with right and left screw-threads 6 0, receiving thereon clamp 130 ing nuts 61, provided with extensions 62, which are apertured to slide upon a transverse rod 63, which is in turn attached to the side pieces 44, as shown. It is thus seen that by turning the transverse rod 58, the clamping nuts 61 may be moved into engagement with the links 55, to hold the same against movement. It is obvious that by turning the rod 58 in the proper direction,'the links 55 may be released, whereby the forward table top 51 may be swung upwardly or downwardly to assume the desired angular position, subsequently to which the rod 58 may be turned to lock the links against movement. Connected with the rear end of the table top 48, as shown at 64, is a suitably stiff retractile coil spring G5, having its opposite endconnected with the cross bars 18, as shown at 66.

The numeral 66 designates a sternum support, which is preferably suitably upholstered or padded. This sternum support is pivoted or hinged to the forward table top 51, and for this reason the same has forwardly extending bars 66"` attached to the lower surface thereof, which bars are provided at their forward ends with apertures for receiving the transverse shaft 50. Surrounding this transverse shaft is a suitably stiif coil spring 66, having a central U-shaped portion 66d which engages the lower surface of the forward table top 51 while the free ends 66e of the same engage the lower surface -of the sternum support 66a, thus servingv to yieldingly support the same. Means are provided to lock or rigidly hold the sternum support in its horizontal or'upper position, the same come prising links GGf and 66g, which have a knee-joint, as shown at 66h, whereby the links are capable of bein@ swung upwardly to assume an angular position but cannot bc swung downwardly below the position shown in Fig. 4. The upper end of the link 6G is pivotally connected with the sternum support G63, as shown at 661, while the lower end of the link 66g 'is rigidly connected with a transverse shaft 66j. The ends of the shaft 66j are journaled through portions of the side pieces 44 and extend outwardly therebcyond to be rigidly connected with cranks 66. Vhen the links 66 and 66g are moved to their locked positions, pressure upon the sternum support 66a will tend to hold them in this position, until they are swung upwardly by manipulation of theI shaft 661'.

Pivotally mounted upon the transverse shaft 23 to swing in a vertical plane, is a main toothed parabolic sector 67, which permanently engages a forward locking toothed parabolic sector 68, which is 'pivotally mounted to swing in a vertical plane upon a transverse shaft 69, as shown. Surrounding 'the transverse shaft 23 is a suitably stiff coil spring 70, having a centrally ar-y ranged U-shaped portion 71, which is attached to the free end of the main parabolic sector 67. The free end portions 72 of this spring extend downwardly and are engaged by cams 7 3, which are rigidly mounted upon a rock-shaft 74. This rock-shaft is normally held against turning movement by clamping bolt or bolts 75. Rigidly connected with the opposite ends of the rockshaft 74 are bellcrank levers 7 6, adapted to be moved 'in either direction by the Afoot. rlhe spring is always under tension so that the same tends to swing the supporting structure 12 upwardly, the free end of the sector G7 engaging transverse bar 77, the ends of which dare apertured for receiving the portions 1G of the tubular rods 18. By swinging the bell-crank lever 76 in either direction, the cams 73 will engage the end portions 72 of the spring 70, whereby the tension of the spring may be altered or adjusted.

The numeral 78 designates a suitably stiff coil spring, which surrounds the shaft 69, with the end portionsV 79 thereof extending downwardly to engage adjusting stops or cams 80. Each of these cams 80 is pivotally connected with the upper portion of the frame 11 by means of clamping bolts 80, whereby' said cams may be angularly adjusted and locked in the desired position, for regulating the tension of the spring 78. The coil spring 78 is provided with a central U-shaped portion 81, which engages the free end portion of the sector G8, tending to turn the same in the direction for turning the sector 67 whereby the latter will swing the supporting structure upwardly.

Longitudinally movably mounted upon the forward portions 15 of-the tubular rods 18, is a transverse bar 82, to which is swiveled a longitudinally extending operating rod 88, having a screw-threaded portion 84, operating within a screw-threaded opening formed through the transverse bar 18. At its outer endv the rod 88 is provided with a handle 4or hand wheel 85, as shown. It is thus seen, by turning the hand wheel 85 the rod 88 will be moved longitudinally to move the transverse bar 82 longitudinally of the portions 15 of the rods 18. Connected with the forward end of the stationary frame 11 is an upwardly extending spring latch 86, the upper end of which is bent in the form of a head 87, adapted for insertion within a recess 88 formed in the transverse bar 82. It is thus seen that when the supporting structure 12 is swung downwardly the transverse bar 82 will automati cally move the spring latch 86 laterally so that the head 87 thereof may enter the opening 88. By proper rotation of the hand wheel 85 the lbar 82 may be moved longitudinally of the portions 15, ofthe rods 13 to move the head 87 out orn the openings 88, whereby the supporting structure will be Jfree to be swung upwardly.

The operation of the apparatus is as tollows VVhen the vertically swinging supporting structure 12 is swung to its horizontal or lowermost position, the same will be held in such position by the spring latch 86`. By -proper manipulation of the hand wheel 85 the supporting structure 12 may be released whereby the same may be swung to a vertical position or to a desired angular position. It is obvious that both of the table tops .33 and 5l may be angularly adjusted and also moved longitudinally of the vertically swinging supporting structure l2. The sternum support 66a may be locked in its uppermost position or yieldingly supported in any desired angular position below the uppermost position.

It is to be understood that the form of my invention herewith shown and described is Ato be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
